Conveyor belt vulcanizer - conveyors - belting - splicing - vulcanizing - hot splicing - presses Manufactured by our special technology, our endless cold-rolled spirals have thefollowing features compared to traditional spirals: 1) Good smooth finish, uniform shape and high precision. It's conducive to materialconveying, reduce the product damage, and to increase the transporting efficiency.2) Easy installment, improve the work efficiency and reduce the production cost.3) Under the physical and chemical surface treatment, the spirals enhance the anti-rustproperty and improves the appearance of screw conveyors. 4) After cold rolling, the spirals will be hardened, which will enhance greatly therigidity and the wear-resistance, say by one time. The HB value is 240.
